Add Subject Types CRUD UI with Tailwind CSS

[Copilot]

Problem

The Subject Types feature was not accessible through the UI, making it impossible for administrators to create and manage subject types (Theory, Lab, etc.) which are essential for proper subject categorization and routine generation. The backend API was already implemented, but there was no frontend interface to interact with it.

Solution

Implemented a complete Subject Types management interface using Tailwind CSS, providing administrators with an intuitive way to create, view, edit, and delete subject types.

Changes Made

Frontend Components (New)

1. client/src/pages/SubjectTypes/SubjectTypeList.tsx

   • Card-based grid layout displaying all subject types
   • Color-coded visual indicators (Theory = blue, Lab = purple)
   • Empty state with helpful onboarding messaging
   • Edit and delete actions for each subject type
   • Responsive design that adapts to different screen sizes

2. client/src/pages/SubjectTypes/SubjectTypeFormDialog.tsx

   • Modal form for creating/editing subject types
   • Form fields:
     • Subject Type Name (text input with validation)
     • Is Lab Subject (checkbox)
     • Prefer Consecutive Slots (checkbox)
   • Real-time validation with error messages
   • Clean Tailwind CSS styling matching the design system

3. client/src/components/Layout/MainLayout.tsx

   • Added "Subject Types" menu item to sidebar navigation
   • Icon: 🏷️ for visual consistency

4. client/src/App.tsx

   • Added /subject-types route

Technical Details

• Styling Framework: Migrated from pure Material-UI to Tailwind CSS as requested, while maintaining Material-UI Dialog component for modal functionality
• Icons: Used Material-UI icons for consistency with existing codebase
• Form Validation: Client-side validation ensures data quality before submission
• Error Handling: Displays user-friendly error messages from API responses
• Code Patterns: Follows existing patterns in the codebase for maintainability

Backend Status

The backend was already fully implemented with:

• ✅ SubjectType model with fields: name, is_lab, default_consecutive_preferred
• ✅ Complete CRUD API endpoints at /api/subject-types/*
• ✅ Repository, service, and handler layers
• ✅ Request/response DTOs with validation

No backend changes were required.

Subject Types List Page (Empty State)

The empty state provides clear guidance on how to get started with creating subject types.

Add Subject Type Form Modal

Clean, modern form interface with clear labels and helpful descriptions for each field.

Form with Sample Data

Form validation ensures data quality before submission to the backend.

Testing

• ✅ Client builds successfully
• ✅ Dev server runs without errors
• ✅ Navigation to Subject Types page works correctly
• ✅ Form modal opens/closes properly
• ✅ Form validation works as expected
• ✅ API integration uses correct endpoints

Impact

This change enables administrators to:

• Create custom subject types (Theory, Lab, Practical, etc.)
• Configure lab-specific settings for proper scheduling
• Set preference for consecutive time slots
• Edit existing subject types to update configurations
• Delete unused subject types

Subject types are a prerequisite for creating subjects, making this a critical feature for the system setup workflow.

Related Design Documents

Implementation follows the design specifications in DESIGN_v1.md and DESIGN_v2.md, specifically:

• Subject Type table schema with is_lab and default_consecutive_preferred fields
• REST API endpoints for subject type management
• Integration with the subject creation workflow
